Job 5:19
19. in six . . . yea, in seven— (Pr 6:16; Am 1:3). The Hebrew idiom fixes on a certain number (here "six"), in order to call attention as to a thing of importance; then increases the force by adding, with a "yea, nay seven," the next higher number; here "seven," the sacred and perfect number. In all possible troubles; not merely in the precise number "seven."
Proverbs 30:15
15, 16. horse leech—supposed by some to be the vampire (a fabulous creature), as being literally insatiable; but the other subjects mentioned must be taken as this, comparatively insatiable. The use of a fabulous creature agreeably to popular notions is not inconsistent with inspiration.
There are three . . . yea, four—(Compare Pr 6:16).Proverbs 30:18
18-20. Hypocrisy is illustrated by four examples of the concealment of all methods or traces of action, and a pertinent example of double dealing in actual vice is added, that is, the adulterous woman.
